OF PERU, INDIANA SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 250,562, dated December6, 1881.

Application filed July 9, 1881. (Model.)

To all whom it may concern:

Be it known that I, LAWRENCE MCCALL, a citizen of the United States,residing at Peru, in the county of Miami and State of Indiana, haveinvented certain new and useful Improve ments in Sash-Fasteners; and Ido hereby declare that the following is afull, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofrelerence marked thereon.

Figure 10f the drawings is a front elevation of a window frame and sash,partly in section, showing the application of my invention. Fig. 2 is adetail view of the spring-rod-fastening device, with a portion of thewindow-sash in dotted lilies, showing the position of the fasteningdevice. with relation to the notches upon the sash. Fig. 3 is aperspective view of the window-frame, with the molding connected theretofor concealing the fastening device; and Fig. 4: is a plan view of thesame with the molding removed.

The present invention has relation to that class of sash fasteners orlocks composed of a spring-arm or other like device adapted to engagewith notches or a serrated bar on the window-sash for holding it at anyheight or fastening the sash closed, as desired.

Previous to my invention the particular construction of these fasteningdevices rendered them very expensive as well as difficult in applying tothe window-frame. Ordinarily these fasteners were provided with a knob,button, or other device for operating them, which were disposed upon theoutside of the Window-frame in view. Therefore it was an easy matter fora person on the outside of the window to break one or more of the panesof glass, reach his hand through, release the fastening device bypressing upon the knob or button, disengage it from the sash and raisethe same, thereby affor ding no security against thieves unless thewell-known locking devices operated with a key are employed, which arenotonlyexpensive and com pl,icated,as a general thing, but are at timesimpracticable.

The object of my invention is to provide a simple, cheap, and practicalfastening device that can be readily attached to the windowframe withcomparatively slight alteration of the same, thereby enabling it to besold in sets in the marketready for immediate appli cation to thewindow-frame, and when thus connected and the window-sash fastened thesash cannot be opened by any one on the outside by breaking a paneofglass and reaching his hand through, as the manner of connecting it tothe window-frame completely conceals it from view, requiring a suitablekey to operate it. These objects I attain by the constructionsubstantially as shown in the drawings and hereinafter described.

In the accompanying drawings, Arepresents the window-frame, and B thesash, said frame having connected thereto a suitable molding, a, whichextends around its four sides. The sash B is provided upon one of itsedges with inclined notches b and a notch, c, with which the fasteningdevice engages when it is desired to fasten the windowclosed,theinclinednotches serving to hold the window-sash open at any height required.

The fastening device is of peculiar form, it being composed of a steelor other spring-wire, O, of sufficient length to give it the requiredelasticity. The wire 0 is disposed within arecess, d, formed in theframe A, the lower end ofthe wire being bent at right angles, as shownat 9, so that it may be driven in the frame A, this being all that isnecessary to securely fasten the wire to the frame. The opposite orupper end of the wire 0 is bent at aright angle, as shown at e, andagain at right angles, as shown atf, Fig.2. The wire forming thelastmentionedangleis of sufficientlengthto form a wide and firm bearingfor the face of the notches b,and consequentlyacompletelock for thesash.

An opening, h, is formed in the frame A at the upper end of the recessd, and at a right angle thereto, to receive the angle f of the wire andallow it to move horizontallyin the opening to releaseit from the.inclined notches b or notch 0.

The moldings a 'i, which are ordinarily used in window-frames, serve tocompletely conceal the fastening device from view.

To operate the fastening a suitable key is necessary, its shank beingflat and inserted into the narrow opening k through the molding i, andby pressing down or outward the angle fof the Wire 0 the same will bedisengaged from the notches in the sash.

too

As the fastening device is wholly concealed by the moldings a z", shoulda person from the outside break the glass for the purpose of raising oropening the window the fastening device could not be operated withoutpossession of the key, thereby making the fastening a very secure oneagainst parties from the outside.

The manner of bending the wire 0 is deemed of importance, it not onlyforming a complete fastening device, but one that is simple, easy ofattachment to the window-frame, and that can be manufactured atatrifling cost, there being no additional springs or other devicesnecessary to render it operative, or screws or other similar fasteningsfor securing it to the sash.

The entire fastening device, as will be seen, is composed simply of apiece of spring-wire bent in theform shown, and. as heretofore, there isno knob or button on the end of the fastening for operating it, nor isit composed ot'sheet metal. This latter form, although common,is

not COUSidrlQd practical, as the sheet metal is not as strong anddurable as the wire, and besides there is increased expensein theirmanufacture, as well as making it, in most cases, necessary to usescrews to connect them to the window-sash, while my device is connectedby the staple end 9. Having now fully described my invention what Iclaim as new, and desire to secure by Letters Patent, is-

1. The combination, with the window-sash B, having the notches b c, ofthe spring-wire 0, having the staple end g, for attaching it to thewindow-frame, and atits opposite end beat, as shown and described, toform the two angles ef, said wire being disposed within the recesses d hof the frame and concealed from view by the moldings ad, the latterhaving an opening, 7c. through it for the reception of a suitable keyfor operating the fastening device, substantially as and for the purposeset forth.

2. As an improved article of manufacture, a sash-fastening deviceconsisting of the springwire 0, bent, as shown and described, to formthe two angles 6]", and at its opposite end bent to form a staple, g,for attaching it to the window-frame, substantially as and for thepurpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
